Bio: Petty thief and get-rich-quick opportunist Rudy Jones was
working a janitorial job at S.T.A.R. Labs when he decided to steal some
experimental biochemical and sell them to a S.T.A.R. competitor.
Surprised by Superman, Jones fled the robbery scene, accidentally
contaminating himself with the chemicals in the process. The chemicals
permanently transformed Jones into an energy parasite, one who must
regularly drain the life force from another living being in order to
One touch of the Parasite's hands will leave a victim weakened and
prolonged contact will kill them. When he drains his prey, Parasite not
only takes on that person's energy, but their knowledge, memories, and
any skills or powers they might have. Naturally this makes Parasite a
deadly foe for Superman, for he cannot only weaken the Man of Steel but
then turn around and fight him with his own stolen powers. In this state
the Parasite also becomes temporarily aware that Clark Kent and Superman
are one in the same, and so poses a deadly threat to Lois, Jimmy or
anyone else close to Clark.
